Anderson has been on a free-agency tour across America over the last week. He stopped in Baltimore, Miami and Tennessee but has yet to find a new home. There's a chance he could re-sign with the New England Patriots, too.

Here's a picture of the free-agent meeting with defensive coordinator Dave Wannstedt outside of Tempo Restaurant in Buffalo last evening (via the Buffalo Bills' Twitter account):

Anderson would be the ideal right defensive end to plug in opposite Mario Williams in the Bills' new 4-3 alignment and is easily the best pass-rusher left on the free-agent market.

The 6'4'', 255-pound former Chicago Bears fifth-round pick will turn 29 in May and is coming off one of the best seasons of his career in 2011 within Bill Belichick's system. Anderson totalled 10 sacks and forced two fumbles for the Patriots.

However, his best year in the NFL came as a rookie with Chicago in 2006, when he accumulated 12 quarterback takedowns and had four forced fumbles. After being cut by the Bears in 2010, when a drop in sacks coincided with the emergence of Israel Idonije, Anderson joined the Houston Texans and former University of Alabama teammate DeMeco Ryans. That year, Anderson tallied four sacks and 21 tackles.

It's likely that Wannstedt wants more depth across his defensive front in the form of prototypical 4-3 defenders, but Anderson certainly fits the mold. If he signs, the Bills will have one of most talented and ferocious defensive lines (on paper at least) in the AFC, if not the entire NFL.

Are we witnessing the first example of the Mario Williams influence on Buffalo?
